About

We only measure. That’s the whole idea.

Certis is an independent laboratory. We test peptides and research chemicals — we don’t make them and we don’t sell them. That gap is deliberate: with nothing riding on the answer, the answer means something.

How we keep it honest

Every test runs on a written, validated method and a qualified instrument. Identity, purity and contamination are confirmed by techniques built on different physics, so a single quirk can’t decide a result.

Every figure on a certificate traces back to the method that produced it and, where it’s a quantity, to a traceable reference standard. Someone other than the analyst reviews the work before it’s released.

What happens to your sample

Each one arrives under its own reference and moves through its tests with a documented chain of custody. A portion stays with us, and the records are kept for seven years — so a result can always be looked at again.
